DETAILED DESCRIPTION OF THE EMBODIMENTS

(7) Exemplary embodiments of the present disclosure will be described hereinafter in detail with reference to the attached drawings, wherein like reference numerals refer to like elements. The present disclosure may, however, be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein; rather, these embodiments are provided so that the present disclosure will convey the concept of the disclosure to those skilled in the art. In addition, in the following detailed description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of the disclosed embodiments. However, it is apparent that one or more embodiments may also be implemented without these specific details.

(8) Embodiments of the present disclosure include a low-profile, angled (e.g., right-angle) connector assembly including a header and a corresponding mating connector mateable thereto. The header defines a shroud for receiving a mating end of the mating connector. The shroud is defined by a generally three-sided wall or structure, having a vertical opening for receiving the mating end in an insertion direction, and a lateral opening for receiving a body of the mating connector in the mated position. Unlike prior art headers which typically define a shroud with a continuous circumferential wall (e.g., a four-sided wall), the three-sided or C-shaped shroud or plug according to embodiments of the present disclosure permits the mating end of the second connector to be placed directly adjacent a mounting base of the header, resulting in a low-profile arrangement. The mating connector defines two hoods or covers on respective sides thereof to create improved retention with the three-sided shroud. Specifically, the two hoods engage with and hold sidewall ends of the header shroud in a mated position. In this way, the mating connector joins the free ends of the shroud, and functions as a fourth side of the shroud, creating a robust structure that retains the mating connector with respect to six potential degrees of freedom; three in translation (i.e., along each of the X, Y and Z-axes of FIG. 1) and three axial rotation (i.e., about each of the X, Y and Z-axes) with respect to a center of the header, for example.

(9) Referring generally to FIG. 1, an electrical connector assembly 100 according to an embodiment of the present disclosure includes a first connector or header 110, and a second or mating connector 150 electrically connectable thereto. The header 110 includes a base 112 including an outer mounting flange 113 defining one or more mounting features, such as a plurality of apertures 111 receiving corresponding fasteners for securing the header to a mounting surface, for example, a housing of an electrical component or device. As would be understood by one or ordinary skill, electrical conductors or terminals 300 (see FIG. 4) extend through an opening 135 of the header 110 and comprise first ends for mating with corresponding conductive terminals 302 of the mating connector 150, and second ends for mating with a conductor of the electrical device or component, such as a bus bar arranged within a housing of the device (not shown). The mating connector 150 may be electrically fitted to a free end of one or more conductors or wires 10 to be connected to the electrical component for electrically interconnecting the component to a remainder of an electrical system.

(10) The mating connector 150 comprises a main body 154 defining a mating end 170. The body 154 extends from the cable or wire 10 in a direction L (or along the Y-axis direction), generally parallel to an axial direction of the cable. The mating connector 150 further defines an end cap 152 removably fixed to the main body 154. The mating end 170 of the mating connector 150 is configured to be frictionally-fitted into a shroud 120 of the header 110 in a mating or insertion direction I (or along the Z-axis direction), generally perpendicular to the axial direction of the remainder of the body 154 and/or the cable 10. In this way, the connector assembly 100 according to the exemplary embodiment defines a “right-angle” or 90 degree-type connector. The mating end 170 of the connector 150 includes locking elastic tabs or latches 172 for engaging with a corresponding locking features 119 formed in or on each side of the shroud 120 of the header 110, as will be set forth in greater detail herein.

(11) With particular reference to FIGS. 1 and 3, the shroud 120 extends from a first side of the base 112 and defines a circumferential wall partially surrounding the opening 135 formed through the header 110 for receiving the mating end 170 of the mating connector 150 in an interior space thereof. The shroud 120 of the exemplary embodiment is a generally three-sided (C-shaped or open-ended) wall including a pair of opposing sidewalls 124 and an end wall 125. Each of the sidewalls 124 may define a receiving slot or slotted opening 126 into which a portion of the mating end 170, for example, a latching portion including latches 172, may be received for engaging with the corresponding locking features 119 of the sidewall 124. Each of the receiving slots 126 of the sidewalls 124 may comprises a height that is less than a height of the remainder of the shroud 120. This reduction in height may be provided to accommodate the latches 172 of the mating end 170, as shown in FIG. 1. The end wall 125 extends generally between, and normal to, the pair of sidewalls 124. An open end 128 is defined by the shroud 120 on a side thereof opposite the end wall 125. The open end 128 is sized to receive the body 154 of the mating connector 150 in the mated position, as shown in FIGS. 1 and 4.

(12) Each sidewall 124 of the shroud 120 further includes an end portion 130 arranged opposite the end wall 125 and defining the open end 128. In one embodiment, each end portion 130 may extend from one of the sidewalls 124 in an oblique or angled manner with respect to a segment of the sidewall 124 immediately adjacent thereto, or with respect to a general direction of extension of the sidewall 124 along the Y-axis (i.e., the axial direction of the body 154 or cable 10). In this way, each end portion 130 extends in directions along both of the X and Y-axes. The end portions 130 may extend in at least partially-opposite directions, for example, along opposite directions along the X-axis, resulting in the open end 128 increasing in width as it opens toward the exterior of the header 110. In other embodiments, the end portions 130 may extend from a remainder of the sidewalls 124 in a non-angled manner.

(13) As is most clearly shown in FIG. 3, a top or apex 131 of each sidewall 124 may be defined directly adjacent each end portion 130, with each end portion defining a generally declining surface or angular edge segment 133 extending downwardly from the apex 131 to a free or end edge thereof. The apex or vertex 131 extends to a height greater than a height of the remainder of the sidewall 124, or of the shroud 120 in total. The apex or vertex 131 may be realized via a top edge of the sidewall 124 having a curved or rounded profile, or at via a juncture of an inclined angular segment 132 and the segment 133, with the segment 133 extending obliquely from the angular segment 132 in at least two directions.

(14) As shown in FIGS. 1, 2 and 4, the body 154 of the mating connector 150 defines covers or hoods 160 configured to receive each of the end portions 130 of the shroud 120 therein. Specifically, each cover 160 defines a channel 162 sized and oriented to receive the end portion 130 between opposing walls thereof. In one exemplary embodiment, each cover 160 is sized and located so as to provide a friction or interference fit with the inner and outer-facing surfaces of the end portion 130, aiding in the retention of the mating connector 150 and the header 110. A closed top end 164 of each cover 160 has a profile corresponding to a top edge of the end portion 130, for example, to the angled edge segment 133. Specifically, the top or cover end 164 may comprise a similarly declining segment 165 corresponding to the segment 133, and a second segment 166 extending therefrom obliquely therefrom and corresponding to a remainder of the raised or protruding apex 131 of the sidewall 124. In this way, and as can be visualized from the figures, an interior top end of the channel 162 corresponds in profile to the top edge of the sidewall 124 and/or end portion 130 thereof for achieving abutting engagement therewith over their lengths. In one embodiment, the protruding apex 131 of the sidewall 124 is positioned directly adjacent to an end of the second segment 166 of the cover 160, with the apex extending to a height greater than that of the cover 160 relative to the base 112 of the header 110.

(15) With particular reference to FIG. 4, with the end portions 130 engaged or captured within the corresponding channel 162 of the mating connector 150, the end portions and openings define mating surfaces opposing one another in multiple directions (e.g., the X and Y directions). This arrangement prevents both translation and axial rotation of the header 110 relative to the mating connector 150 in the illustrated mated state with respect to each of the three axes. In this way, the mating connector 150 defines, or functions equivalently to, a fourth sidewall of the shroud by mechanically joining the free end portions 130 of the sidewalls 124 together. As further shown in FIG. 4, the sidewalls 124 and slots 126 of the shroud 120 define opposing interior walls or wall segments 117 configured to frictionally engage with corresponding opposing wall features 157 of the mating end 170 of the mating connector 150 therebetween. Similar opposing or complementary slotted features 159 are defined adjacent the end wall 125.
